Last modified
CVE-2021-34371 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Neo4j through 3.4.18 (with the shell server enabled) exposes an RMI service that arbitrarily deserializes Java objects, e.g., through setSessionVariable. An attacker can abuse this for remote code execution because there are dependencies with exploitable gadget chains.. EPSS estimates a 13.39% chance of exploitation in the next 30 days.
